Abstract: Various aspects described herein relate to cancelling interference in wireless communications. Energy level detection of a received signal can be performed to determine an allocation size and position corresponding to an interfering device in the received signal. An interference demodulation reference signal (DM-RS) and cyclic shift of the interfering device in the received signal can be determined. It can be determined whether to apply successive interference cancellation on the received signal, based at least in part on the allocation size and position and the DM-RS and cyclic shift, to cancel interference from the interfering device.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. Some aspects more specifically relate to discrete Fourier transform spread orthogonal frequency division multiplexing (DFT-S-OFDM) waveform pre-equalization for MIMO communications. A receiver device, such as an extended reality (XR) device, may be configured to offload a portion of data processing to a companion device, such as a user equipment (UE). In some aspects, the UE may generate a DFT-S-OFDM waveform and may apply a pre-equalization to the DFT-S-OFDM waveform. Applying the pre-equalization to the DFT-S-OFDM waveform may include applying a minimum mean square error (MMSE) pre-equalization to the DFT-S-OFDM waveform. The receiver device may receive the pre-equalized DFT-S-OFDM waveform from the UE and may process the pre-equalized DFT-S-OFDM waveform. For example, the receiver device may decode the pre-equalized DFT-S-OFDM waveform without performing fast Fourier transform (FFT) or inverse discrete Fourier transform (IDFT) operations.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit first control information that is indicative of noise (e.g., phase noise, additive white gaussian noise (AWGN), or both) that impacts a spectral efficiency of a modulation and coding scheme (MCS). The MCS may be associated with a constellation of points that may be each representative of a respective candidate sequence of bit values encoded with a corresponding combination of signal amplitude and carrier phase. The UE may receive, based on transmitting the first control information, second control information that indicates a set of partitioning parameters indicative of a hierarchical partitioning of the constellation into a multiple subsets of points. As such, the UE may decode a message, modulated via the MCS, using the hierarchical partitioning indicated by the set of partitioning parameters.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for early termination of decoding attempts, including decoding attempts associated with physical downlink control channel (PDCCH) candidates that are encoded using a rateless code. In some aspects, a transmitting device may encode a message using a rateless code associated with a cumulative encoding of various portions of the message, and using a device identifier or group identifier as an input to the encoding. Similarly, a receiving device may receive an encoded signal over candidate resources and may attempt to decode the signal in accordance with the rateless code and using a device identifier or a group identifier as an input to the decoding. As such, intended or non-intended receiving device may be able to evaluate whether to proceed with a decoding attempt or to terminate a decoding attempt at a relatively early stage.

Abstract: Certain aspects of the present disclosure provide techniques for envelope tracking schemes for a node in a wireless communication network. One aspect provides a method for wireless communication by a transmitter device. The method generally includes: combining envelopes associated with subbands of an input signal to be amplified for transmission based on a combination function; amplifying, via an amplifier, the input signal to generate a transmission signal, the input signal being amplified based on a combined envelope signal, representing the combination of the envelopes, received at a supply input of the amplifier; and transmitting the transmission signal to a receiver device.

Abstract: A user equipment (UE) may transmit, to a network node, an indication of support for a decoder success prediction capability. The network node may obtain the indication of support by the UE for the decoder success prediction probability. The network node may output a transmission for the UE including one or more parameters based on the indication of support by the UE for the decoder success prediction capability. The UE may receive the transmission including one or more code blocks based on the indication of support for the decoder success prediction capability. The network node may optimize a multiple incremental redundancy scheme (MIRS) schedule for at least one of transmitting the transmission or retransmitting the transmission based on the indication of support by the UE for the decoder success prediction capability. The transmission may include the MIRS schedule.
